As part of Vitesse's HawX family of switches, the HawX-G24 enables intelligent local area network (LAN) switching solutions focused on quality of service (QoS), network security, and management to maximize network performance, utilization, and efficiency. With its sophisticated management feature set, the HawX family can be used for a variety of metropolitan area network solutions and control plane applications, in addition to desktop and workgroup switches.
Managed LAN switches using the HawX-G24 can be used to easily upgrade enterprise networks, providing GbE to the desktop utilizing the existing cable infrastructure. Overall, network performance can be increased with minimal IT spending. HawX-G24 supports 24 ports of triple-speed 10/100/1000 Mbps SGMII/SerDes interfaces, wire-speed performance, and on-chip memory. Features include jumbo frame support, link aggregation, flow control, spanning tree, and port-based access control. All the HawX switches provide unparalleled QoS features necessary for building cost-effective layer 2 managed switch solutions. Key QoS benefits include programmable multi-layer classification with 8 priorities, minimum guaranteed bandwidth allocation, per queue shaping and policing with Committed Info Rate (CIR) and Peak Info Rate (PIR) policies, and Differentiated Services Code Point (DSCP) remarking.
The VSC7374 includes an extensive suite of software solutions, development tools, and technical support. Software API and SDK solutions are available and nearly 100% compatible to all other HawX-G24 Vitesse Ethernet switches. Vitesse reference designs, coupled with the API and SDK solutions, enable vendors developing their own hardware and software systems to begin design immediately. For customers wanting simpler development, turnkey software solutions are available through 3rd party vendors.
